How to Remove and Replace Serpentine Accessory Drive Belt on BMW, DIY Video

BAVauto recommends replacement of the serpentine accessory drive belts and tensioner/idler pulleys at 60,000 mile or 4-year intervals. Replacement is very easy and straight forward on most models. In this video, we’ll show you the procedure on a 2001 3.0 Z3 with the M54 6-cylinder engine. Other early-’90s through mid-’00s six cylinder models are similar, as are the V8s. Later model 4, 6 and 8 cylinder models (N20/26, N51/52, N62/63, etc) and MINIs have differences that are outlined in the applicable Bentley publishers repair manuals.
